If I want to create my own class MyWidget which inherits from QWidget
Tutorial tells me to write constructor like this...
MyWidget::MyWidget(QWidget *parent)
: QWidget(parent){....}
I'm wondering what is the role of : QWidget(parent)
Does it mean explicit call for QWidget's constructor?
What are the benefits of storing XML in SQL Server over storing JSON in a varchar field?
Any tutorial available for how to use the XML data type effectively?
Do I need to provide the dtd / xml schema somehow? I've heard it is optional, right?
Thank you.
I'm reading through a tutorial on using voice commands to control applications and, in an example of controlling rhythmbox, it suggests commands such as the following can be executed:
rhythmbox-client --play
rhythmbox-client --pause
Why does this not simply open a new instance of the program, and how can I emulate the functionality in my own programs? For example, how could I pass a string to a particular instance of a program?
Thanks
I am looking for a PHP example/tutorial which can accept hi-scores/survey upload from an iPhone. Hopefully, the PHP script:
accepts POST, in additional to GET
works over SSL (https)
connects to MySQL
In addition, it'd best the iPhone can get a session from the server and submit the session value along with the hi-score. Thanks

I'm new in iOS development and i need simple example (project) with explained two-entity coreData with to-many relationship between A and B entities on iOS6 with storyboard interface and ARC. In storyboard should be two UITableView controllers which present entities A and B and two UIViewControllers which present adding string data from text fields
I searched in many books, sites, video lessons like "lynda.com", but i still not understand how and where i should implement two-entity coredata with one to-many relationship in code.
Can someone give me link to understandable tutorial or put the project on GitHub?
I'm using :
$(window).scroll(function () {
if ($(window).scrollTop() + 10 >= ($(document).height() - $(window).height())) {
loadContent();
}
}
It works fine with Chrome, IE, Firefox but except in Safari. In function loadContent, I used JSON to load data, as this tutorial. But while I test in Safari, It takes the content twice from JSON. If the other takes 9 items, then Safari takes 18 items.
Does anyone know how to solve this problem?
Thanks.

How should I go about this? I mean how does the control know whether someone is logged in or not? Session ID? Cookies?

Hi there
I have a question to the following procedure:
script/generate scaffold product
title:string description:text
db:migrate
#then I generate a migration which adds a column description to the
table products and migrate the db
again.
My question is: why is the field description not added to the project-views? Is that normal rails scaffold behaviour?
I think I saw in a video tutorial that the scaffold updates as well the views, which would be very convenient.
Thanks in advance for any help!
All I want to do is allow the user to browse through their folders to look for a file, select it and then press submit which saves the file to my server as well as the path to the saved file.
How would someone do this? (Some sort of tutorial website would help a lot)
So, I've been doing android application tutorials and everytime I create a package, for example the helloAndroid tutorial is com.example.android. When it saves this to src it creates a folder for com, another for example and one last one for android. So it gives me the error "class com.example.android does not exist" because its broken into different folders.
If anyone can help me out please email me at: [email protected]
Thank you very much.

Is there a library or good tutorial which covers creating in-app settings, like this:
http://img.skitch.com/20090625-s8bf6ahybwe3cesd1id38h3nt.jpg
What I would like is if it:
doesn't use the built-in Settings app
is controlled by a plist file with various Dictionaries and Arrays
creates a nice looking table view
allows text fields as well as switches and sliders and ticks etc
doesn't have any of the annoying problems I've come across when trying to build my own version (not scrolling to show the textfield, cells disappearing)
It would appear that the iphone dev world is crying out for such a thing.
THANK YOU!
